Many years ago I was killing time in the IBM bldg atrium next door to NYC Trump tower; it had tables for public in the days before vagrants, amidst bamboo and even a computer museum open on weekends. I was about to bolt for opening time at the Metropolitan Museum when I saw a security man swing open a hidden door from Trump lobby to IBM atrium. I zoomed thru in order to save steps walking around bldg, eyes riveted forward to clear thru the ugly bordello-like marble decor and pop out the main entrance.
It was deserted except for one tall frizzy blond man with armful of documents who straightened up in an escalating haughty scowl as we passed. No eye contact, and I dimly realized I was invading Trump personal space, but he wasn't much on my radar and I had a higher mission to focus on. Later I learned that his first wife designed the lurid decor, and it perhaps had the same function as some Roman ruin props at the entrance of my parents retirement home complex - make a certain unwelcome demographic uncomfortable. Probably explains decor in a biker bar, etc... not that the customers like it but it scares away the folks who don't fit in.
In the early opening time at Metropolitan museum, probably on another visit but maybe the Trump one, I encountered artist Andy Warhol. I was just exiting the deserted Egyptian temple which was bathed in yellow light, and the approaching pasty be-wigged celebrity urgently locked eyes with me. It would be logical that his concern was that I leave him alone with his trailing photographer to do poses. But it felt more like he as a needy person was feeding off my recognition of him. I recently thought of an even less palatable motive, but anyway I blazed past as a sightseer on a higher mission.
Other features of NYC in the past were the higher crime rate. Before the pacifier effect of cellphones, women walked in fear, and as a long legged male you couldn't help but tailgate slower walking women almost quaking in fear as you finally passed. I had to do the quick walk sometimes, when I would go to saturday night musical events in Harlem and Bedford Stuyvesant. If the doors weren't open yet, you had to keep orbiting or else be swarmed by lounging troublemakers.
